Specification of Letters Patent.

Patented May 11, 1909.

Application filed February 28, 1908. Serial No. 418,258.

To all whom it may concern: I

Be it known. that I, FRANCES M. WELDON, a citizen of the United $tates, residing at] Canton, in the county of Van Zandt, State of Texas, have invented certain new and g useful Improvements in Billing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled i in the art to which it appertains to make 1 and use the same.

The present invention has reference to} baling presses and it aims, generally, to. provide an exceedingly simple, readilyoperated, and effective machine of that class designed for baling hay. i

More especially, however, the invention j resides in the particular mechanism employed for operating the plun er, and in the provision of means for bodiy raising the '3 door of the baling chamber prior to itsl detachment therefrom and to the removal of the bale, this latter feature being of considerable importance owing to the fact that such doors, as ordinarily constructed, are so heavy and unwieldy that their disengagement from the fasteners by which they are held in place 1 can not be effected without difliculty.

The invention will be readil understood from a consideration of the ollowin detailed description, and its preferred embodiment is illustrated in the accompanying drawings in which like arts or features, as the case ma Y be, are esignated by corresponding re erence numerals in the several views.

Of the said drawings :--Figure 1 is an end elevation. Fig. 2 is a longitudinal vertical section. Fig. 3 is a horizontal section through the upper portion of the baling chamber, showing the guides, and the rollers carried by the slldin rod. Fig. 4: is an enlarged detail view 0 the door. Fig. 5 is a fragmental rear elevation of the baling chamber, showing the vents.

Referring more particularly to the drawings, 1 designates, generally, the supporting base of the machine which, as shown, comprises a pair of oppositely-disposed U- sha ed frames, the corresponding arms of which are bolted together at their free ends and thus form the side sills of the base, while the front and rear sills thereof are formed in like manner by the bight porof the side and bottom plates.

tions of said frames. The front sill carries the swinging truck 2, while the rear frame is provided upon its under face with brackets in which the rear axle 3 is journaled, said axle carrying the ground wheels 4. The baling chamber, which is likewise mounted upon the rear frame, comprises a pair of vertical sides 5 bolted at their lower ends to the corresponding side sills or arms of said frame, a bottom plate 6 which rests upon said sills and is likewise secured thereto, and

a back 7 which is bolted to the rear edges The upper portion of each side 5 is longitudinally slotted, as indicated by the numeral 8, in which slots travel rollers 9 secured to the opposite ends of a horizontal shaft 10 which fits in a passage formed through the vertical stem portion 11 of the plunger 12. Said stem is hinged at its upper end to the adjacent end of the lower member of a pair of plates 13 whose mutuaIly adjacent inner ends are likewise hinged together and are further provided with alining vertical slots 14 which communicate with each other and thus form a continuous slot through which one end of a pitman 15 passes. The upper plate is ivoted at its upper end upon a rod 16 W ose opposite ends fit in bearing openings formed through the up er ends of a pair of vertical extensions 17 ormed upon the tops of the chamber sides 5. The plates thus form a toggle or break-joint which is operated by the pitman 15, the end of the latter which passes through the slot 14 carrying a vertical late 18 whose inner face bears against the hinged ends of the plates 13. Plate 18 is rovlded with a vert1calslot 19 through i which the pitman end passes, said end being provided with a series of perforations in which a pin 20 is interchangeably engaged, said pin fittin in a transverse groove formed in the outer ace of plate 18. The bolt 38 of the hinge between the plates 13 likewise passes through one of said perforations, to connect the pitman to said plates. The 0 osite end of the pitman is pivoted to t e ifurcated upper end of a dependin operating lever 21 provided adjacent suc point with perforated trunnions through which the pivot rod 22 passes, the opposite ends of said rod passing through the perforated front and u per ends respectively of pairs of horizonta braces 23 and vertical braces 24:, the lower ends of the latter being bolted to the front frame member of the base 1 while the rear ends of the former are bolted to the corresponding sides 5 of the baling chamber. A downward movement of the operating lever in the direction of the arrow, Fig. 2, will therefore break the joint between the plates 13 and raise the plunger, which latter will be lowered when upon a move ment of the lever in the opposite direction.

The front of the baling chamber is partly open, as shown in Fig. 1, the plunger being held in lace during its vertical movements by a pair of longitudinal guides 25 which are secured to the inner faces of the chamber sides 5 at the front edges thereof, and ex tend to within a very short distance of the top edge of the door 26 which closes that portion of the chamber in which the compression takes place. This door, which is completely removable from the chamber, is provided upon its front face with upper and lower cross-beams 27 and 28 which project at opposite ends beyond the corresponding side edges of the door, the projecting ends of the lower beam resting upon the arms of the rear frame member of the base, while those of the upper beam rest upon the projecting ends of the horizontal cross beams 29 which are secured to the sides 5 of the chamber, the door being held against outward movement when in itsclosed position by blocks or shoulders 30 carried by the above-mentioned frame member, and by up standing pins 31 set into the beams 29, said shoulders and pins being adapted respectively, to engage the projecting ends of the beams 28 and 27.

As originally stated, the invention contemplates the provision of means for bodily raismg the door 26, at the conclusion of the pressing operation, sufiiciently far to release the beams carried thereby from enga ement with the pins and shoulders, and to t is end a lever 32 is mounted upon the end sill of the rear frame member in such a manner that its forward end extends beneath the lower end of the door, as shown in Fig. 2. Said lever is provided intermediate its ends with laterally projecting pins or trunnions 33 which extend through eyes 3% formed in the free upper ends of the arms of a U-sha ed bracket 35 which is secured to the outer ace of said end sill in whose upper face is formed a transverse groove 36 which acts as a seat for the lever. The outer or handle end of the lever is elevated somewhat by reason of the slight increase in depth of said groove at its end adjacent to the door, the inner end of the lever being curved upward slightly to permit the door to rest squarely thereon. The application of downward pressure u on the handle end of the lever will there ore raise the door bodily, as will be a parent.

The back 7 of the baling cham er is provided with two or more longitudinal slots 37 through which the air escapes during the pressing operation.

The swinging truck 2 carries a forwardlyextending yoke by means of which the machine is connected to a traction engine and moved bodily from place to place.

The operation of the machine is thought to be apparent from the foregoing and further description thereof is accordingly deemed unnecessary.
